# 3ab math

Counting to 5 Module 1 capitalizes on the energy and excitement young students have as they enter their first day of Pre-K by providing a playful and active yet carefully sequenced structure through which children progress. Note that only the base is affected by the exponent. Many students make the error of multiplying the base by the exponent. When we write a literal number such as x, it will be understood that the coefficient is one and the exponent is one. This can be very important in many operations.

## Tests in factoring polynomials

It is also understood that a written numeral such as 3 has an exponent of 1. We just do not bother to write an exponent of 1. Now that we have reviewed these definitions we wish to establish the very important laws of exponents.

These laws are derived directly from the definitions. First Law of Exponents If a and b are positive integers and x is a real number, then To multiply factors having the same base add the exponents.

For any rule, law, or formula we must always be very careful to meet the conditions required before attempting to apply it.

Note in the above law that the base is the same in both factors. This law applies only when this condition is met. These factors do not have the same base. An exponent of 1 is not usually written. When we write x, the exponent is assumed: This fact is necessary to apply the laws of exponents. If an expression contains the product of different bases, we apply the law to those bases that are alike.

Find the product of several monomials.

## (3ab)(2ab)= - solution

A monomial is an algebraic expression in which the literal numbers are related only by the operation of multiplication. To find the product of two monomials multiply the numerical coefficients and apply the first law of exponents to the literal factors.

Do you remember the first law of exponents? Multiply 5 times 3 and add the exponents of x.Resources cover SOL Testing, Writing, Reading, Language Arts, Social Studies, Math and Science.
